square end on full splice cues

[desi2960]

i bought 500 one piece cues from an antique pool table restorer, i was told most of these cues were made from the 1920's to the 1940's as are the old tables he restores.
i am trying to find out when makers [ and they were dozens ] of the old one piece full splice cue stared using the square splice at the butt end of the splice.
thank you chuck


sorry wrong section
